COMPRESSOR FOR COMPRESSING BEAN AND OTHER SUBSTANOES INTO PACKAGES.

SPECIFICATION forming part of Letters Patent No. 291,683, dated January8, 1884.

. l Application filed June 5, 1883. (No model.)

ofaZZ whom it mag/concern: Be it known that I, GENRY A. CHAPMAN, ofStrawberry Point, in the countyof Clayton andState of Iowa, haveinvented certain new 5 and'useful Improvements in Compressors forGompressing' Bran and other Substances into Packages, of which thefollowing is a full, clear, and exact description. i y

This invention has more especially for its Io object the compressing oi'bran and otherlight `substances into packages which may either u besquare, cylindrical, or other desired shape in their transverse section,and may be niade shaft is fitted to slide longitudinally in its bearingsb Z, and carries or has connected with it a frame, e, which is free toslide with the 5 shaft, and within which and fast on the shaft, so as torotate with it, are inner and outer l large and small bevelgears, E Eand F F. y The longitudinal movement of the shaft D and l frame e,carrying the gears E E and F F 6o along with it, to the right or to theleft, as required, is controlled by a lever, f, connected with an arinfrom the frame c. u is an upright shaft, fitted to rotate and capable ofsliding up and down within bear- 6 ings g g, attached to the main frame.Fast on is shaft is a combined spur and bevel gear, I-I EI; or it may beseparate gears. The spur gear or portion II gears with a horizontalspur-gear, I, arranged to workin between the 7o upper cross-ties, (l C,and through which, as a nut, a screw-threaded pistoirrod, J', works, andthe bevel gear or portion II gears with either ol" the wheels E la" or Flil/,accordingly as said wheels'arc slid to the right or to the left,and the gear I-I l-I is raised or lowered for the purpose. Said gear I-IH may be made to drop or lower ofits own weight onsuitabl. lowering astep bearingarin, 71 on which the shaft G rests, and which is connectedwith an 8o l up-and-down slide, K, on one of the uprights A. rlhis slideis lowered. or raised as required to adjust the bevel-@ear I-Irelatively to the gears E E and F F by means of a bellcranklever, L. Thepiston-rodJ has asquare- 85 shaped piston, J', on its lower end,arranged to work within and up out of a correspondinglyshapediilling-tube, M, which may be of l l thin metal, and which is capable ofbeing adjusted up and down by a windlass, N, and 9o ropes or chains 13i, attached at their one end to the windlass, (which may be controlledby pawl and ratchet,) and, after passing around sheaves s, are made fastat their opposite end to a crossslide, O, that carries the filling-tube,and that is guided by and arranged to slide up and down within theuprightsAA. When the piston J'l is within the :filling-tube or fillerlM, it and its rod are of course prevented from turning as the wheel Iis rotated to raise or roo lower the piston; and to prevent the pistonI5 Will here be'described as being sacks of square or right-angledshape, with bottoms to corre spend, and which it is my intention to makethe subject of a separate application for Letters Ifatent. 2o Theinvention, by way of illustration, will also here be described as usedfor the compression of branV into such packages; and it consists incertain novel constructions and combinations ofpaits in acon1pressor,and in 2 5 a method of filling and closing the package, i whereby greatsimplicity and eiiiciency are obtained and the packages may be sealed under aheavy pressure, which gives great density to the-mass. f'

l 3o Reference is .to be had to the accompanying `corresponding parts inall the figures.,

` igure l is a front view of a compressor 3 5 constructed in accordancewith inyinvention, and as in the act of compressing bran into a sack orpackage of square shape in its transverse section. Fig. 2 is a verticalsection of the same on the line x x in Fig. 1; and Fig. 3 4o horizontalsection, in part, on thelineyj/in ig. l. A A are the sides or uprightsof the frame of the compressor; B, its base, and C C u1 e percross-ties, connecting the uprights A A. 45 Saidframa however, may beotherwise suitt ably constructed.

is the main 0r operating shaft, arranged to occupy a horizontal positionon erin bearings b b, projecting outward from and in front 5o of the:main iraine, which shaft may be rotated by hand applied to a crank, c,or by any suitable motor powerapplicd toa pulley, d; This tion of therod is made square,

' of which is of a capacity to fit snugly over suitable material ortached sack,

the lower portion of the filler M, and which has a square top andbottom, may be made of sack-cloth, ducking, burlap-cloth, or othermaterials.

T is a hinged or opening and closing clamp, arranged externally of thesack 'when on the filler, and of about the same depth as the sack, tohold the sack in position and to support or stiffen the filler againstthe pressure exerted within it by the compression ofthe bran.

In the operation of the compressor the filler or tube M is drawn up toits top or extreme upward limit by the windlass N, and the clamp T, ifin place on it, removed. The sack S is then drawn up over the lower endportion of the filling-tube M, so that the bottom of the sack comes incontact with the lower end of said tube, after which the tube, with theatis let down onto the base B of the compressor. The clamp T is thenapplied around the sack and locked. The bran to be packed is now chargedwithin the tube M from its top, which may be done by a spout, and whichis continue( until the filler M is full, or sufficiently s'o to l thesack after compression. Then the sack cover or top S', which issquarc'and somewhat larger than the filler, is placed upon the loosebran in the filler, and the lever f is moved to the left and engagedwith au outer lleft-hand side locking-pin, a. The lever L is also movedto the left until the bevel-gear H engages with the large bevelwheel E.Motion then being communicated to the shaft D, the wheel I will berotated to work down the piston J into the iilling-tube M for a distanceof about one-fourth the depth of said tube, more or less. The lever f isthen adjusted onto a second locking-pin, c2, to slide the frame e andits inclosed gearing somewhat to the right, and the bevel-gear I'I' israised into mesh 'with the smaller bevel-wheel F. This will cause thepiston J' tobe carried down slower and'with greater power as the resistvance increases, land is continued unt-il the piston J reaches the top ofthe body of the sack or to a level with the top of the clamp T. Thegears are then `adjusted so as to stop the motion of the' piston, andthe filling-tube M is lifted by the windlass N out of the sack, and theclamp T is' opened and removed. This leaves the sack-body with the brancompressed within it and under heavy pressure, ready for the top S to besewed on, after which the leverf is adjusted onto the locking-pin a3,and

It, suitably placed for the lever L suitably moved to put the bevel-gearl-l' in mesh with the reversing small wheel F', to back up the piston alittle when the sack is removed. Another sack-body is then drawn onto orover the lower end of the filling-tube, and said tube is let down ontothe floor or base B again and the clamp T applied and seeured,'afterwhich the lever f is adjusted into lock with the pin a* and the lever Ladj usted to bring the bevel-gear II into mesh with the reversing largerwheel E', for the purpose of ruiming the piston quickly out of thefilling-tube, which then is charged with bran, the sack-cover placed ontop of the tube, and the compressing action repeated, as before.

A sufficient pressure may be obtained by this compressor to reduce thebulk of the bran in the sack, so that its weightwill be even greaterthan a sack of like size filled with the grain itself, and the bran maybe compressed, as described, into sacks or packages of both small andlarge dimensions.

The compression, place without the bran coming in contact with the sidesof the sack and without any strain being thrown upon said sides, and thebottom of the sack is also supported from strain by its resting on thefloor or base of the compressor,

it will be observed, takes and the cover of the sack is secured whilethe 1 bran is under heavy pressure.

I-Iaving thus described my invention, I claim as new and desire tosecure by Letters Patent- 1. In a compressor, the combination, with thesides A, baseB, and reciprocating piston J', of the filler-tube M,receiving within it the piston, the sack S, receiving the tube extendedto its bottom, a detachable cover, S', and the clamp T, substantiL llyas shown and described.
